Mitsubishi Heavy Industries Ltd. will exhibit at this month's Paris air show a cabin mockup of a passenger jet it is developing, company officials said Monday.

The Tokyo-based manufacturer wants to gauge interest for the proposed airliner, which would have around 90 seats and would be Japan's first commercial jet in decades, project general manager Masakazu Niwa said.

"This will be a cutting-edge small jet that combines top-class economy with outstanding cabin comfort," Niwa said at a news conference.
